We have checked hotels in downtown Nafplion but noticed lack of parking and noisiness till late at night. They say you can part at port for free but it is hard to find a place and takes a lot of precious time. In Harmony parking is right outside of your window. Walk to the sea is two min across the road.
This place was perfect especially for those who likes a small 10 - 15 min stroll after the dinner.
It is two story so you do not need to wait for elevator (which they have). Breakfast was included and was modest but acceptable with good coffee and fresh juice. View is very commendable, from you window take pictures of port, sea shore, town and fortresses on the hills. Service and attitude of staff was superior. These is café and supermarket within less that five min and plenty of good and very good diners in the city in 15 min walk.
One of major archeological destinations, Tiryns is within walking distances or 5 - 10 min drive, Mycenae is in 20 min drive. Also close to several vineries. In general this may be perfect location for those who wants to walk and/or drive around
